Figure 2

Parameter estimation. Illustration of peak parameter estimation. The figure displays a well-resolved peak in the region $\mathcal{R}=\{i:941.3\mathit{Th}\le x_i\le 941.9\mathit{Th}\}$. In this example, the size of $\mathcal{R}$ equals 33, i.e. there are 33 pairs {(x _i ,y _i )}that enter a nonlinear least squares problem of the form (4). Under the assumption of an EMG model, the resulting fit is indicated by a solid line.
